GAVELING MECHANISM FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 283,866, dated August 28, 1883,

Application filed May 25, 1883. (No model.)

To ail whom it may concern Be it known that I, JOHN S. DAVIS, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improve- 5 ments in Gaveling Mechanism for Grain-Binders, of which the following is a specification.

My invention mainly relates to improvements applicable to platform-binders for packing the grain in gavels in binding-receptacles,

i and especially adapted for use in connection a Patent No. 274,441.

In the accompanying drawings, Figure 1 is a'view partly in rear elevation and partly in vertical section, showing those features of a binder with which my improvements have 2 connection. Fig. 2 is a view partly in side elevation and partly in section on the lines 2 2 of other figures. Fig. 3 shows the rotary packer carrier or wheel detached from its shaft with one of the freely-pivoted packer arms in place.

0 Fig. 4 shows the packer-wheel in section. Fig. 5 is a view partly in front elevation and partly in section on the line 5 5 of Fig. 2. Fig. 6 is a view as seen from the inner side of one of the casing-disks or cover-plates of the packerwheel detached.

A binder-arm, A, its suitably-actuated rockshaft a, agavel-actuated trip-arm, I), and cooperating mechanism for starting the binding mechanism, a binding-receptacle, B, a grain 4o passage-way, O, leading thereto from the endless carrier of the grain-platform, a suitablyoperated rotary packer-shaft, c, grain-parting arms D D,-loosely mounted on this shaft, and their attached curved rods d (Z, together con- 4 5 stituting a passageway cut-off and gavel-isolating mechanism, and a rackbar for actuating said mechanism from the binder-arm, are all similar to or substantially the same as heretofore-employed devices. (See my prior pat- Instead of providing the rotating packershaft 0 with rigidly-connected packer-arms, as

in my formerly-patented improvements, I now provide packerarms of the pivoted type, and

so construct the packing mechanism as to guard 5 5 against entanglement of stalks of grain there. with. Furthermore, the packer-sh aft is maintained at a fixed distance from the binder-arm shaft by a bracing connection between these shafts, so as to prevent the springing of the packer-shaft by the expansive pressure on the packer-arms of the accumulated grain, which spring of the packer-shaft has heretofore occasionally interfered with the proper co-operation of the parting-arms of the gavel-isolating mechanism and the binder-arm. Any de sired number of packer-arms are provided.

In this instance there are eight arms in two sets or groups of four each. These sets are exactly alike, and in describing the packing 7o mechanism detailed description of one set of arms only is needed.

Two rotary packer carriers or wheels, E E, are removably secured at a suitable distance apart, by keys or otherwise, upon the packer- 7 '5 shaft. Each wheel carries a set of packerarms, F, which are loosely pivoted, at equal distances apart, cl ose to the periphery of their wheel by pivot-studs 6. Each arm F has a curved-ended heel-projeetion or controlling- I lug, f, projecting from one side, near its pivot, and'on the opposite side of its pivot has a shoulder or ear, Short ribs or stop-pro jections G are provided on the carrier-wheels. There is one such stop G for every packer-arm, 8 5 arranged close to its pivot-stud e, so as to be borne against by the stop-shoulder y or the heel-lug f, as further on to be explained.

At the opposite sides of each packerca-rrier E there are provided circular casing-plates or 0 packer protecting disks H and I. These plates are loosely mounted on the packer-shaft by sleeve-hubs h and 13. Each carrier is provided with a hub, J, of a length sufficient to keep the centrally dished and hubbed disks at 5 the proper distance apart to leave a space between them to accommodate the packer-arms, Each plate H is formed with a peripheral flange, K, inclosing and protecting the carrier-wheel, and between this flange and the opposite surface ofthe disk I a peripheral space is provided, by way of which the packer-arms are projected beyond and withdrawn within their sectional casing, as further on to be explained.

In order that the guide-lug L for the rackbar M may be readily secured in place by the same fastening which secures one of the plates I in the desired position relatively to the adjacent packercarrier, the sleeve of this guidelug, fitting loosely about the packershaft, extends into the sleeve or hub of the plate, abuts against the hub of the carrier, andis secured to the plate-hub by a set-screw, m. The packer-shaft between the guide-lug L and the rearmost one of the casing-plates His protected by loose sectional. sleeving, and in front andv rear of the packing-casings short sleeves NN, removably secured to the paokershaft by cross-pins n n, abut against the hubs of the front plate, H, and rear plate, I, respectively, of the two casings for the packer-arms. The sleeve-section O carries the parting-arms D D of the gavel-isolating and passage-way cut-off mechanism. vented from turning about the packer-shaft, as further 011 will be explained, and each plate I is provided with a cam, 1?, shown as formed with it by a rib having the somewhat abrupt inward curve at its heel or lowermost-end, p,

' ends, nuts, and perforated lugs u to the plates.

beneath the packer-shaft, and with the downwardly-projecting angular termination 19 at its point or upper end. i

To assist in the clearing of the packer-arm from the grain after it has been pushed along the passageway and forced into the receptacle, the plates H I are formed with the camshaped lugs or'eccentric projections Q at their edges next the receptacle and. above the level of the receptacle-bottom. The arms, after they ,are freed from the action of the cam 1 drop and withdraw within the periphery of the eccentric portions of their casings, as further on will more fully be explained.

The sectional casings for the packer-arms are held in place, and the packer-shaft is braced by connection with the shaft a in the following way: Side lugs, R R, upon the outer faces of the plates H II, and similar lugs, S S, upon the plates I I, have braces or stay-straps T T, respectively, secured to them by bolts and nuts t t. Additional brace-rods U, one for each plate I, are secured by their threaded The rock-shaft frame tube or sleeve V is provided with lugs 12, for making connection between the rock-shaft and the outer ends of the straps T and rods U. Only one of these lugs is shown, as the location of the-other is obvious. The outer ends, w, of the brace-straps curve or bend upwardly after passingbeneath the rock-shaft tube and rest-against the lugs v. These bent ends of the brace-straps are slotted longitudinally. The outer ends of the rods U are threaded, pass through perforations in the lugs '22, and through the slots of the brace-straps, and the parts are adjustably and detachably secured by means of two nuts, yy, and a washer, Y, for each lug.

The plates H and I are pre-.

From the above description it will readily be understood that the various attachments of the packer-shaft may readily be seen red in 130 sition and removed, and that yield of the packing mechanism in a direction away from the binder-arm shaft is impossible.

In operation the packer-arms (rotating in the direction indicated by arrows) are actuated in part by gravity, in part positively, and in part by the pressure of the grain against which they work. Starting with a packer-arm in the position in which the retracted one (marked 00) is shown in the drawings, it will be understood that its controlling lug or heel projection, when first presented to the cam P, is acted upon by the angular end 1) thereof and the arm thus quickly projected from thecasing. Durin g the time theheel-lug bears against the cam the arm is held in position to act on the grain. During the time the heel-lug is held by the pressure ofthe grain against the curved end 19 of the cam the arm is being gradually with drawn from contact with the grain and into its casing, as will be understood by inspection of Fig. 5, in which the path of the points of the arms is indicated by the dotted line .2. During the times the packer-arms are retracted, so as to be within their casings at their points, their heel-arms bear against the stops G, and are thus held in position to be directed by the hereinbefore particularly described, nor to the employment of all features of my invention, as some of my improvements may be used without others, and essential and novel features thereof be employed in connection with machines differing fromthat herein described.

I claim as of my own invention- 1. The combination, substantially as hereinbefore set forth, of the packer-shaft, the packercarrier, the packer-arms freely pivoted to the carrier, the open-peripheriedsectional packercasing, supported on the packer-shaft, and means for controlling the vibrations of the packer-arms, for the purpose described.

2. The combination, substantially as hereinbefore set forth, of the rotary packer-shaft, the packer-carrier, the stationary sectional packer-casing, open at its periphery, the freelypivoted packer-arms, and means by which they are projected from their casing to act upon the grain and then allowed to gradually withdraw within the casing, for the purpose described.

, 3. The combination, substantially as hereinbefore set forth, of the packer-shaft, the packer-carrier having the stops, the stationary tion with the casing-cam and the carrier-stops,

for the purpose described.

4. The combination, substantially as herein- -before set forth, of the packer-carrier, the

packer-arms, the plates constituting the stationary sectional packercasing supported on the packer-shaft and having the eccentric edge projections, and means for controlling the vibrations of the packer-arms, for the purpose hereinbefore set forth. a
